HANDLER PROGRAM FOR REMOTE INPUT MANAGEMENT SYSTEM This invention is a digital computer program and, more particularly, a digital computer program for passing data to and from remote terminals in a data processing system.
ln accordance with this invention, provision is made for the transfer of computer commands and data between a centrally located computer and a plurality of remote terminals.
The program of this invention maintains the status of any number of connected terminal devices. In a closed loop process, it repetitively determines first whether any terminals are to be supplied an output. If an output is to be supplied, the program controls checks as to the validity of the output data. If the data is found to be valid, the output function is performed.
Following the output process, the program then determines whether any input devices have data for transmission to the computer. If so, the program causes execution of a subroutine to accept the inputs, the subroutine chosen depending upon the type of device delivering the input.
Material essential to the understanding of this invention is found in US Pat. No. 3,585,601, filed Aug. l9, [969, for Remote Input Management System, which material is herein incorporated by reference and made a part of this application.
More specifically, reference is made to Section V of said U.S. Pat. No. 3,585,60l, including Subsections 1, 2 and 3. Subsection 3, therein, contains the associated program source listing in ALGOL. The listing may be readily compiled by any computer which will accept that language.
The drawing herein is the flowchart of the outer block of the Handler program. In addition, reference is made herein to FIGS. 11A, 11B, 12, 13A and 13B in the abovccited U.S. Pat. No. 3,585,60l for further disclosure herein.

8. The method of claim 7, further comprising the step of controlling the transmission of initial control characters to the terminal for which it had been determined that output is ready for delivery thereto.
9. The method of claim 7, wherein said step of controlling transfer of a portion of said ready output data to an output bufier comprises the steps of controlling substitution of characters within said ready output data when the original characters cannot be received by the terminal to which the data is being transmitted, and,
a determination of whether further portions of output data are to be transferred to the terminal to which the current portion is being transmitted.
10. The method of claim 7, wherein said step of controlling transfer of the portion of said ready output data from said output buffer to the terminal comprises the steps of controlling writing the portion of said ready output data on said terminal, and,
a determination of whether more portions of output data are to be transfered to said terminal.
11. The method of claim 10, further comprising the step of controlling transferring of further portions of ready output data to the output buffer if it is determined that more portions of output data are to be transferred to said terminal.
12. The method of claim 1, wherein the step of controlling transfer of digital information to a terminal for which it is determined that output is ready comprises the steps of controlling a determination of the class of terminal for which it had been determined that output is ready,

transmission of a poll inquiry to each terminal determined to require polling,
determination as to whether output is ready for delivery to each terminal, and
transmission of data to each terminal for which data is ready.
